Metastatic static cancer is a fear of every cancer patient. Metastasis makes it hard for cancer to be treated. However cancer cannot metastasize without angiogenesis which is the sprouting of new blood vessels. The oncologists can best avoid metastasis by avoiding angiogenesis which is only achieved by use of angiogenesis inhibitors.
Angiogenesis is a process through which blood vessels are formed. Angiogenesis occurs naturally during the growth and development of children. The mother’s womb has to form new blood vessels that are important in the development of the infant. This is a crucial process in the foetus. However in adults this process happens less often and may happen during wound healing. In women it happens during the menstruation cycle. When this formation of new blood vessels is induced by tumor, it is referred to as tumor angiogenesis. This happens when the tumors release molecules that signal the surrounding tissues. It is this signaling that activates genes that make proteins to initiate growth of new blood vessels. These new blood vessels penetrate into the cancerous cells and help them grow by supplying them with the needed nutrients and removing wastes out of them hence creating an environment that favors their growth and metastasis.
Without angiogenesis tumors cannot grow and metastasize, it is therefore a necessity without which the cancerous cells will become inactive and will even die. When the new blood vessels have been formed it become hard for the cancer to be treated. The cancer patient will have to endure pain as the tumors will be growing at a faster rate since they have adequate nutrient supplies which they receive though these newly formed blood vessels therefore they can be controlled when these nutrient supplies are cut and that is what angiogenesis inhibitors does.
This discovery that cancer cells depend on angiogenesis to grow and metastasize has led to development of many cancer treatments that target angiogenesis. These therapies can be very effective in fighting this disease since it doesn’t affect the healthy body cells. Moreover if angiogenesis can be inhibited then all cancers can be controlled since it is a necessity for growth of tumors in all cancers. When angiogenesis is inhibited the cancer cells are denied of their supplies and they will automatically die of starvation.
Copper is a trace element the needs to highly regulated as any slight homeostatic copper disruptions may result in serious health complications such as the Wilson’s disease. Copper is necessity for angiogenesis. Without copper angiogenesis cannot take place. It is therefore evident that Copper fuels cancer tumor growth and metastasis. Angiogenetic inhibitors can be used to curb this situation. Tetrathiomolybdate (TM) is effective in copper chelation. Researchers have proved that TM forms a stable tripartite complex with copper and protein. When given with food, it chelates food copper with food protein and inhibits absorption of copper in the bloodstream. There is endogenous secretion of copper in saliva and gastric secretions associated with food intake, and this copper is also chelated by TM when it is taken with meals, thereby preventing copper re-absorption.
Medical researchers have done test on the effectiveness of the tetrathiomolybdate (TM) on mice that were injected with cancer cells and left for a week for angiogenesis to begin. After the new blood vessels had been formed the mice was injected tetrathiomolybdate (TM). The angiogenesis stopped and the tumor growth stopped. However from researches that had been done in the past it was concluded that tetrathiomolybdate (TM) has a unique action on the copper that fuels angiogenesis and retarded tumor growth with minimal side effects. When cancer patients are given TM with food they get a negative copper balance which is not good angiogenesis. The copper that is bound by TM cannot do any meaningful biological activity as it cannot be absorbed by cells and is excreted in the urine having been cleared by bile hence tamed.
Normally, the level of copper that is needed for angiogenesis is much higher as compared to the amount of copper that is needed for cellular activities that are dependent on cancer like cytochrome function and heme synthesis. Cancer therapy that are based on anti-copper may work well as the copper needed for cellular activities will be retained even when TM is used to as an anti-copper angiogenic agent.
It has also been found out that Low molecular weight heparins helps in improving the cancer patient’s chances of survival as it inhibits metastasis. The low molecular weight heparins are able to inhibit metastasis by preventing cancer cell triggered destruction of the endothelial glycocalyx. In experimental animal models and clinical tests; it was found that the low molecular weight heparins protects against cancer progression and metastasis. The scientists say this is possible as the low molecular weight inhibits metastasis interfering with the cancer cell binding on the platelets. Cancer cell needs to attach themselves to the platelets to move to other parts of the body. Low molecular weight heparins also inhibit metastasis through binding of heparanase or hyaluronidase thereby protecting the vascular endothelium from invasion by the cancer cells.
